COUPLING HOOK OR BUTTON FOR CHECK-ROW CORDS.

SPECIFICATION forming part of Letters Patent No. 236,025, dated December28, 1880. Application filed September 3, 1880. (Model.)

To all whom it may concern Be it known that I, GEORGE D. HAWORTH, ofDecatur, county of Macon, State of Illinois, have invented certain newand useful Improvements in Coupling Hooks or Buttons for Check-RowCords, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, making part of thisspecification, in which- Figurel is a perspective view, showing two ofthe couplinghooks, forming, when connected as shown, the button, knot,or knob of a cord or wire used in connection with acheckrow cornplanter. Fig. 2 is a perspective view of one of the hooks detached.

The present invention consists in casting the parts or hooks forming thebuttons or knots of a check-row cord or wire with open hooks, throughwhich they can be coupled together, and with eyes, through which theyare secured to the check-row cord or Wire, each in a single piece, inform adapted for use as hereinafter explained.

It has been usual heretofore to cast the parts of the knot or button forcheck-row cords or wires with the eye formed in it and a spur upon it,which, after being annealed or rendered malleable, was bent into theform of an open hook, substantially such as is herein represented, acheck-line knot or button formed by this last-named process being shownin Letters Patent granted to me October 8,1878, No. 208,814. Thisprocess was found to be expensive and tedious, and by makinga slightmodification in the form of the parts I am now enabled to cast thecoupling-hooks in the exact form required for the necessity for therebyfacture.

In the accompanying drawings, a represents a coupling-hook, formingone-half of a knob or button used on check-row cords or wires foruniting the sections thereof and for operating the dropping devices of acorn-planter. These hooks or half-buttons are provided each with use,thereby obviating annealing and bending, and materially reducing thecostof manua bell, cone, or cup shaped base, which forms the knot orbutton for actuating the seeddropping devices, said base having acentral eye or perforation for the reception and retention of theknotted end of the wire or checkrow cord, and from one side wall of theopen cup a tapering spur, 12, extends in curved or hook form until itsrecurved end is in close proximity with the wall of the cup at itsopposite side, or nearly so, as shown, just sufficient space being leftbetween said end and side wall to permit two such hooks to pass by eachother when brought together at their open ends, in position about atright angles to each other, for coupling or uncoupling them, as desired,but serving effectually to prevent their becoming uncoupled when inposition for use. The coupling-hook thus formed is cast in the formshown, which is also the form required for use, and the necessity formaking the hook part malleable and afterward bending it into the formrequired is thus obviated, not only greatly reducing the cost ofmanufacture of the knots or buttons, but avoiding the weakening of themetal consequent upon such bending of the spur into hook form after thebutton has been made in the usual manner and by the usual process.

I am aware that coupling hooks or buttons have been made for use uponcheck-row cords or wires substantially in the form described and shown,but by adilferent process, as above explained, and I therefore do nothere claim such hooks, broadly, and irrespective of the process ofmanufacture; but

What 1 do claim is A coupling-hook, half-button, or knot for check-rowcords or wires, consisting of the perforated cup or base having the opencoupling-hook cast thereon in form adapted for use, substantially as andfor the purpose set forth.
